What WxYapper is

WxYapper is a weather application for the United States that delivers fast, readable forecasts tied to your city or ZIP code. Each location page includes current conditions, a plain-language forecast summary, hourly and daily details, a live radar map, and tools to plan around weather-sensitive events.

You can search by ZIP code, city name, or device location—no sign-up is required to view a forecast or radar.

Who operates WxYapper

WxYapper is operated by Cardinalis Web Development. We build and maintain the website, Android app, mobile web experience, and related services, including the Weather Yapper Alexa skill.

The Android app is available on Google Play.

Data sources

Forecast and observation data come primarily from official U.S. government weather services. That includes grid-based forecasts, current conditions, meteorologist discussions, and related public products.

Radar imagery comes from NOAA/NWS open radar products: a continental (CONUS) reflectivity mosaic when zoomed out, and nearest NEXRAD (WSR-88D) site reflectivity when zoomed in. On the regional view we may also show nearby ASOS/METAR station temperatures and winds. Discussion text from source agencies is public-domain material; we display it alongside our own summary content for reference.

For a walkthrough of the radar map, see How to use WxYapper radar.

How summaries are produced

WxYapper's structured forecast summaries combine meteorologist discussions with local forecast context (temperature, sky cover, and short-range trends). Summaries are generated once per regional forecast area and shared across ZIP codes in that region.

Automated processing turns that source material into plain-language briefings: an overview, a main concern, and short-term and long-term detail aligned with the source discussion. Location names are personalized when you view a forecast (for example, your city name is inserted at read time). Generated text is validated and checked against source data before it is shown.

Summaries are interpretive and meant to help you plan your day. They are not a substitute for official forecasts, watches, warnings, or advisories.

Important limitations

Weather can change quickly. Do not rely on WxYapper alone for life-safety decisions. Always follow official weather alerts and instructions from local emergency management and other authoritative sources during severe weather.
